1256 an empty .plt section.
1257 (elf32_sparc_relocate_section): For a GOT reloc against a global
1258 symbol when no dynamic object was seen, initialize the contents of
1259 the .got section. For a GOT reloc against a local symbol, only

4810 generic_link_add_symbols.
4811 (_bfd_generic_link_add_symbols_collect): New function, like
4812 _bfd_generic_link_add_symbols but also collect constructors and
4813 destructors by name as collect2 does.
4814 (generic_link_add_symbols): New function, like old
4815 _bfd_generic_link_add_symbols but with collect argument.

4828 * archive.c (bfd_construct_extended_name_table): Use ar_padchar
4829 for first character in an extended name.
4830 (_bfd_write_archive_contents): If ar_padchar == '/', then use
4831 "//" as the name of the special archive member holding the
4832 extended name table.
4834 Mon Mar 21 12:28:19 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
4836 Support for link_order types which generate relocs in order to
4837 support -Ur in the linker.
4838 * linker.c (generic_link_add_symbol_list): Remove bitsize argument
4839 from call to _bfd_generic_link_add_one_symbol.
4840 (_bfd_generic_link_add_one_symbol): Remove bitsize argument.
4841 Don't pass bitsize to constructor call back. Pass BFD_RELOC_CTOR
4842 instead of bitsize to add_to_set call back.
4843 (_bfd_generic_final_link): Account for link_order relocs when
4844 allocating space for relocations. Handle them in link_order loop.
4845 (_bfd_generic_reloc_link_order): New function.

4850 argument from declaration.
4851 (_bfd_generic_reloc_link_order): Declare.
4852 (_bfd_count_link_order_relocs): Declare.

4861 call to _bfd_generic_link_add_one_symbol.
4862 (ecoff_bfd_final_link): Account for link_order relocs when
4863 allocating space for relocations. Handle them in link_order loop.
4864 (ecoff_link_write_external): Set the storage class of a defined
4865 linker created symbol based on the section it is in. Correct
4866 bfd_link_hash_weak case to use .sc rather than .st.
4867 (ecoff_reloc_link_order): New function.
4868 * coff-alpha.c (alpha_bfd_reloc_type_lookup): Handle
4870 * coff-mips.c (mips_bfd_reloc_type_lookup): Likewise.

4879 Sun Mar 20 09:24:36 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
4881 * bfd/som.c (som_begin_writing): Fix thinko (off by one error).
4883 * som.c (bfd_section_from_som_symbol): Only to do the value
4884 comparison for function symbols within executables.
4886 * som.c (bfd_section_from_som_symbol): Renamed from
4887 som_section_from_subspace_index. Pass in a native SOM symbol.
4888 For executables, iterate through the sections to find out
4889 which contains the symbol's address rather than using the
4890 symbol_info field. (symbol_info has a different meaning for
4891 dynamicly linked executables.)
4893 * trad-core.c (trad_unix_core_file_p): Don't pass abfd to
4896 * som.c (som_begin_writing): Fix braino (one call to align
4897 space/subspace data was done unconditionally rather than
4898 just for executables.)
4900 * som.c (som_begin_writing): Align text in all executables to
4901 make HPUX kernel happy. Fixes strip/objcopy for shared
4904 Sat Mar 19 07:06:59 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
4906 * som.c (som_begin_writing): Account for alignment needs of
4907 subspaces too when writing executables. Never request a negative
4908 bss size. Fixes some problems with demand paged executables,
4909 still having problems with pure executables and shared executables.
4911 Fri Mar 18 19:12:47 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
4913 * trad-core.c (trad_unix_core_file_p): Call bfd_zmalloc not
4914 bfd_zalloc for rawptr, because later on we may call free, not
4917 * bfd.c (struct _bfd): Add cisco_core_struct to tdata union.
4918 * libbfd.c (bfd_read, bfd_seek): Add comments regarding errors.
4919 * cisco-core.c: New file.
4920 * Makefile.in: Change accordingly.
4921 * configure.in: Recognize cisco_core_vec.
4922 * config/m68k-aout.mt (SELECT_VECS): Add cisco_core_vec.
4923 * targets.c: Add cisco_core_vec.
4924 * bfd-in2.h: Rebuilt.
4926 Fri Mar 18 18:13:49 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
4928 * som.h (som_copyable_section_data_struct): New structure
4929 containing all the private section information which needs
4930 to be copied from input section to output section during
4932 (som_section_data_struct): Remove several fields now in
4933 som_copyable_section_data_struct. Make the space and
4934 subspace dictionaries be pointers (to save space when
4935 only reading objects).
4937 * som.c (bfd_som_set_section_attributes): Now returns a boolean;
4938 some references changed. Allocate a copyable data stucture if
4939 none exists. Store info into the copyable data structure.
4940 (bfd_som_set_subsection_attributes): Likewise.
4941 (som_is_space, som_is_subspace, som_is_container): New functions.
4942 Use these instead of directly accessing private data.
4943 (som_prep_headers): Allocate space and subspace headers here.
4944 Fill in some fields in the space/subspace headers from the
4946 (som_bfd_copy_private_section_data): Only copy the stuff
4947 that we really need to make objcopy and strip work. Allocate
4948 the copy_data structure for the output bfd before copying.
4950 * som.h (struct som_exec_data): New structure to hold exec
4951 info that must be preserved when running objcopy/strip.
4952 (struct somdata): Add new "exec_data" field and accessor
4953 macro. Add some comments on how the various fields are used.
4954 (som_section_data_struct): Make is_space and is_subspace bitfields.
4955 Delete unused subspace_index. All references now use the
4956 target_index field within the section structure itself.
4958 * som.c (make_unique_section): Delete unused declaration.
4959 (som_bfd_copy_private_bfd_data): New function.
4960 (som_object_setup): Allocate space for and save exec information
4961 that needs to be copied during objcopy/strip.
4962 (som_mkobject): Do not allocate space for a file header here.
4963 It is not used when only reading SOM objects.
4964 (som_prep_headers): Allocate space for and attach a file header
4965 to the output bfd. For executables, use the saved system_id
4966 value rather than trying to guess the right value. Do not abort
4967 wwhen setting file_hdr->entry* for executables.
4968 (som_begin_writing): For executables, set the exec_entry and
4970 (som_copy_private_backend_section_data): Always return a value.
4972 * libhppa.h (PA_PAGESIZE): Define.
4974 * som.c (SOM_ALIGN): Define.
4975 (som_begin_writing): If writing an executable, initialize all
4976 fields in the exec header to zero. Update fields in the exec
4977 header as sizes of loadable subspaces are computed. Carefully
4978 preserve alignments when building executables. Actually write the
4979 exec after all the fields are filled in.
4981 * Better long-filename handling. Reads SOM ABI compliant extended
4982 names, but doesn't quite write compliant extended names yet.
4983 * som.c (som_slurp_extended_name_table): Delete function. The
4984 generic code will handle things correctly.
4985 (som_slurp_armap): Seek to the beginning of the next member.
4986 (normalize): New function.
4987 (som_bfd_ar_write_symbol_stuff): Take the size of the extended
4988 name table into account when computing the file offsets in the
4989 SOM dictionary. Make sure to align to an even boundary.
4990 (som_write_armap): Initialize the checksum to zero.
4991 (ar_maxchars): Fix. Opps.
4993 Fri Mar 18 20:35:24 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
4995 * aoutx.h (reloc_type_lookup): Handle BFD_RELOC_CTOR on a 64-bit
4996 machine. Handle BFD_RELOC_SPARC13 and BFD_RELOC_SPARC_BASE13.
4998 Thu Mar 17 18:26:46 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
5000 * bfd-in.h (BFD_VERSION): Use @VERSION@.
5001 * Makefile.in (bfd.h): Replace it with contents of VERSION file.
5002 * bfd-in2.h: Regenerated.
5004 * trad-core.c (trad_unix_bfd_is_local_label): Fixed typo where
5005 this was also named trad_unix_bfd_copy_private_bfd_data.
5007 Thu Mar 17 10:37:07 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
5009 * aoutx.h, elfcode.h, coff-alpha.c, bout.c, ecoff.c, ecofflink.c,
5010 elf32-hppa.c, elf32-mips.c, linker.c, som.c, sunos.c: If malloc(0)
5011 returns NULL, it is not an error. It's possible that some of
5012 these checks are not necessary (because the size can never be
5013 zero), but putting in the checks is the conservative thing to do
5014 in light of the fact that some of these malloc calls replaced
5015 unchecked alloca calls, in which a zero argument would work fine.
5017 Thu Mar 17 11:44:45 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
5019 * osf-core.c (osf_core_bfd_copy_private_bfd_data): Remove
5020 duplicate definition.
5021 (osf_core_bfd_is_local_label): Define.
5023 * reloc.c (bfd_generic_get_relocated_section_contents): Don't fail
5024 if malloc (0) fails. bfd_canonicalize_reloc returning 0 is not a
5025 failure indication, it merely means there are no relocs.
5027 * elfcode.h (NAME(bfd_elf,write_object_contents)): Don't use space
5028 after NAME, since SunOS /bin/cc can't handle it.
5030 Wed Mar 16 16:43:33 1994 David J. Mackenzie (djm@thepub.cygnus.com)
5032 * netbsd386.c (N_SET_FLAGS): Don't nuke the machine id field.
5033 From sukes@glue.umd.edu (Tasuki Hirata).
5035 Wed Mar 16 07:55:54 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
5037 * aoutf1.h (4 places): Use a simple #if on ARCH_SIZE, rather than
5038 all that convoluted stuff with NAME, CAT3, etc. The convoluted
5039 stuff broke for SunOS4 /bin/cc (due to DEFUN elimination, I guess).
5041 Wed Mar 16 00:02:05 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
5043 * som.c (som_prep_for_fixups): Detect section symbols based
5044 on either the lack of private data or the symbol flags. Do not
5045 munge section symbol names anymore -- they no longer confuse GDB.
5046 (som_begin_writing): Leave space for an exec header if writing
5048 (som_slurp_symbol_table): Recognize both forms of section symbol
5049 names "L$0\002" and "$<FOO>$". Change the name of "L$0\002"
5050 section symbols to be the name of the section they represent.
5051 Debugging symbols begin with "L$0\001", not just "L$".
5053 Tue Mar 15 22:58:28 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
5055 * bfd-in2.h, libbfd.h, libcoff.h: Rebuilt.
5057 * bfd-in.h (JUMP_TABLE): Add new entries to the jump table
5058 for bfd_copy_private_section_data, bfd_copy_private_bfd_data,
5059 and bfd_is_local_label.
5061 * targets.c: Add new entries to the bfd_target structure.
5063 * bfd.c (bfd_copy_private_bfd_data): New definition.
5065 * section.c (bfd_copy_private_section_data): New definition.

5073 * *-core.c: Provide default definitions for new functions in
5074 the target vector which all point to bfd_false.
5076 * aout-target.h, coffcode.h, elf32-target.h elf64-target.h, ieee.c
5077 libaout.h, libecoff.h, nlm-target.h, oasys.c, srec.c, tekhex.c
5078 Default new vectors for copying private backend data to bfd_true.
5079 Default new vector for determining if a symbol is a local label
5080 to bfd_generic_is_local_label.
5082 * som.c (som_bfd_copy_private_section_data): New function.
5083 (som_bfd_is_local_label): New function.
5084 (som_bfd_copy_private_bfd_data): For now default to bfd_true.
5086 * elf32-hppa.c (hppa_elf_is_local_label): New function.
5088 Tue Mar 15 23:55:47 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
5090 * cf-m68klynx.c (CALC_ADDEND): Use _bfd_m68klynx_howto_table.
5092 Tue Mar 15 04:41:13 1994 David J. Mackenzie (djm@rtl.cygnus.com)
5095 Replace DEFUN and DEFUN_VOID with K&R-style function definition.
5096 Indent some of them to GNU standards.
5098 * aout32.c, archures.c, core.c, cpu-h8300.c, cpu-i960.c,
5099 cpu-m68k.c, cpu-m88k.c, cpu-mips.c, cpu-vax.c, ctor.c, demo64.c,
5100 elf32-hppa.h, gen-aout.c, host-aout.c, init.c, libhppa.h,
5101 libieee.h, liboasys.h, newsos3.c, som.h, stab-syms.c, sunos.c:
5102 Update copyright years.
5104 Mon Mar 14 11:41:23 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
5106 * som.c (som_prep_for_fixups): A relocation involving the section
5107 symbol for the *ABS* section is really a relocation involving
5109 (som_slurp_symbol_table): Do not set BSF_GLOBAL or BSF_EXPORT for
5110 undefined symbols. Correctly distinguish between debugger symbols
5111 and section symbols.
5113 * som (setup_sections): Set SEC_DEBUGGING and the section attributes
5114 for spaces and subspaces.
5116 * som.c (som_bfd_count_ar_symbols): Fix typo.
5118 * som.c (som_object_setup): Set EXEC_P, D_PAGED, WP_TEXT, and
5119 HAS_RELOC based on the object's magic number.
5120 (make_unique_section): Delete function. BFD and its users are
5121 prepared to handle multiple sections with the same name.
5122 (setup_sections): Allocate space on the BFD's obstack to hold
5123 section names. Use bfd_make_setion_anyway rather than the
5124 obsolete make_unique_section.
5125 (som_prep_headers): Choose the correct SOM magic number based
5127 (som_bfd_fill_in_ar_symbols): Return false, not NULL on error.
5129 Sat Mar 12 09:46:09 1994 Ian Lance Taylor (ian@cygnus.com)
5131 * elf32-ppc.c: Renamed from elf32-powerpc.c.

5141 * sunos.c (sunos_read_dynamic_info): Assume that dynamic info
5142 is always located at the start of the data section to allow
5143 recovery of the dynamic info from a stripped executable.
5144 * ecoff.c (ecoff_styp_to_sec_flags): Handle STYP_PDATA, STYP_XDATA
5147 Wed Mar 9 17:17:53 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
5149 * libbfd-in.h: Remove alloca cruft. It was missing some necessary
5150 cruft (like the #pragma alloca for AIX).
5151 In addition to that problem, the C alloca calls xmalloc, which
5152 means checking for being out of memory can't work right. The
5153 following changes remove all uses of alloca from BFD.
5154 * hosts/solaris2.h: Remove alloca cruft.
5155 * som.c: Replace alloca with a fixed size auto array.

5161 * libbfd.h: Rebuilt.
5163 Tue Mar 8 12:10:38 1994 Ian Lance Taylor (ian@cygnus.com)
5165 * coff-mips.c (mips_relocate_section): Handle MIPS_R_LITERAL like
5168 Sat Mar 5 14:08:54 1994 Peter Schauer (pes@regent.e-technik.tu-muenchen.de)
5170 * elf32-hppa.h, elfcode.h: Replace uses of Elf*_Half, Elf*_Word,
5171 Elf*_Off typedefs by their expansion, the typedefs have been
5172 removed from include/elf/internal.h.
5173 * elfcode.h (bfd_section_from_shdr): Handle SHT_DYNAMIC section like
5174 SHT_PROGBITS section.
5176 Thu Mar 3 20:03:39 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
5178 * som.h (_PA_RISC_ID): Treat HOST_HPPAOSF just like HOST_HPPABSD.

5182 * configure.host: Recognize i[34]86-sequent-*.
5184 * trad-core.c (trad_unix_core_file_p): A non-zero, not zero,
5185 return from bfd_seek indicates an error.
5186 New macro TRAD_CORE_DSIZE_INCLUDES_TSIZE to replace
5187 TRAD_CORE_STACK_OFFSET.
5188 * hosts/symmetry.h: Define TRAD_CORE_DSIZE_INCLUDES_TSIZE and
5189 TRAD_CORE_USER_OFFSET but not HOST_STACK_OFFSET.
5191 Wed Mar 2 11:57:03 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
5193 * som.[ch]: Do not include libhppa.h in som.c, instead include
5196 * elf32-hppa.[ch]: Do not include libhppa.h in elf32-hppa.c, instead
5197 include it in elf32-hppa.h.
5199 * som.c (log2): Return -1 on error rather than aborting.
5200 (setup_sections): Bubble up an error from log2.
5202 * Changes to make HP C compiler happy in both traditional
5204 * som.c (hppa_som_gen_reloc_type): Use correct enum type for
5206 (bfd_som_set_section_attributes): Use unsigned int rather than
5207 unsigned char to avoid GNU-C extensions.
5208 (bfd_som_attach_aux_hdr): Return a boolean to indicate success
5209 or failure rather than aborting on failure.
5211 * som.h (bfd_som_set_section_attributes): Fix prototype to match
5213 (bfd_som_attach_aux_hdr): Add prototype.
5214 (hppa_som-gen_reloc_type): Likewise.
5216 * elf32-hppa.c: Add a couple casts to make HP compiler happy.
5217 (hppa_look_for_stubs_in_section): Do not return false on failure
5218 until rest of code is ready to handle it. Abort for now.
5220 Tue Mar 1 18:33:59 1994 Jim Kingdon (kingdon@deneb.cygnus.com)
5222 * bfd-in2.h: Rebuilt.
5224 Tue Mar 1 13:06:53 1994 Kung Hsu (kung@mexican.cygnus.com)

5503 (b_out_relax_section): If a section contains no relocations, don't
5504 bother processing them.
5505 (b_out_get_relocated_section_contents): Set reloc_done. Assert

6208 The sparc (and possibly other?) NLM format requires a different
6209 way to write exports, so add a write_export field to the backend
6210 data (and set it to NULL for everything but the sparc).
